ARTHUR H. WOODIVARD, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE INTERNATIONALREGISTER COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

REGISTER MECHANISM.

Application filed October 25, 1908.

To all whom it may concern:

Be it known that I, ARTHUR H. Noonwarn, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and uesful Improvement in Register Mechanisms, ofwhich the following is a full, clear, concise, and exact description,reference being had to the accompanying drawings, forming a part of thisspecification.

My invention relates to registering mechanism and contemplates what Ichoose to call a register locking mechanism. This title is applicablebeca .se the mechanism which it designates automatically locks itselfagainst operation at predetermined interrais, not necessarily regular,but, for purposes which will hereinafter appear, purposely irregular.

Although the device of my invention registers, it does not necessarily,of itself, indicate the individual registrations, but is designed toindicate that particular registration which terminates a predeterminedcount and locks the mechanism against further operation. Furthermore,the locking is merely temporarythat is, the mechanism locks itself for ashort period after the interval in which a predetermined number ofregistrations have been made, and it is during this short period thatthe indication is made.

The device of my invention is adapted for association with a primaryindicating register, which indicates each registration and totalizesthem either in trip totals or sum totals or both, for instance such aregister as is employed in street cars and analogous places forregistering payments made to the conductor or other attendant. Thedevice of my invention is adapted to be directly associated with thisprimary register in such a way that it will be operated by the regularregistrations, and I contemplate connecting the locking mechanism of myinvention and the primary register by direct mechanical means.

A primary register, as above referred to, is employed for the purpose ofchecking the payments made to a conductor on a street car or anattendant at a toll gate or similar place, each of the registrationsbeing made by the conductor or attendant si- Specification of LettersPatent.

multaneously with his collection of a fare or toll. Such devices areemployed in large numbers by city traction and railway companies andform, therefore, not only a checking means for the employee himself,but, more particularly, a positive checking means, which the company mayuse, upon the integrity and honesty of the conductors and attendantswhich it employs to make the connections. The conductor or attendanthaving complete control of the operation of this primary registeringdevice, it follows that it would be of absolutely no use unless therewas some means for indicating to an inspector or, indeed, to the payerhimself that the payment has been registered. Although railroad andtraction companies employ detectives or inspectors to ride upon thevarious cars in disguise, these companies rely mostly upon thepassengers to see that the payment of the fare by them is registered. Ofcourse a passenger has no further actual interest in the matter exceptto obtain transportation for his fare, and it need not make anydifierence to him what becomes of his fare so long as he is entitled toride on the car. For the passenger to see or insist that his fare isproperly registered is to him, therefore, merely a matter of casualinterest. It is apparent that this state of afiairs may arise in manydilferent enterprises, as at toll gates, etc, but to facilitate thisdescription I will refer to the employment of my device in a streetcar,so that what will probably be its most popular use will be fullyunderstood.

In order to encourage interest by a passenger to see that his fare isproperly registered, 1'. arovide a device which gives an alarm or signalat predetermined intervals. Associated with this arrangement, the plan,in all probability, would be to offer a premium or reward, for instancea rebate in the way of ride tickets, to the particular passenger whosefare is the last in a predetermined block of fares which comprise aparticular interval, as above outlined. In other words, when aregistration has been made and that registration is immediately followedby the alarn or signal, the person who has just paid his fare is granteda premium or rebate, as pointed out. By this method each passenger uponpaying his fare will be interested in seeing that his fare is registeredto satisfy himself whether or not a reward should be his. In order thata conductor cannot follow the registration which initiates the alarmimmediately by another registration to cut oif the signal, the mechanismis such as to look when the final registration of a block is made. Themechanism remains so locked for a short period, and it is during thisperiod that the alarm orsignal is given. It is" thus that the mechanismwhich I have invented is a register locking mechanism, and the conductoris constrained to wait until the alarm has been given before he canregiste'r another fare. r

In order that the above arrangement may be most effective in practice itis, of course, necessary that the conductor be not aware beforehand ofthe particular registration which will effect the alarm, for otherwisehe might conspire with a confederate to pay a fare at that time. Itherefore contemplate irregularity in the length of the mtervals or, inother'words, a difference in the number of fares in each block whichconstitute an interval. I do not necessarily infer that there should beno repetition, in fact 00- casional repetitionmight be very effective,in the number of fares in a block, but it is the object of my inventionto provide means whereby the number of fares in the various blocks canbe differentiated so that it would be excessively difiicult, if notimpossible, for a conductor to ever acquaint himself with the system ofthe mechanism which he has in charge. The system of each device may,therefore, be considered a cycle in which a predetermined number ofalarms are given, these alarms being so separated as to form a series ofperiods, and these periods may be so combined and permuted that, of avery large number of devices, no two cycles would be precisely alike,and a conductor could never be forewarned as to'just when the mechanismwhich he has in charge will give an alarm.

The device of my invention is mechanically connected, as above stated,with the primary registering mechanism and may be said to consistprimarily of three elements: first, step by step mechanism; second,apportioning means whereby the intervals be tween the alarms maybe'determined; and third, locking means. Secondarily, the deviceincludes an alarm arranged to operate when the mechanism is locked andalso means for timing the alarm period. The various mechanicalcontrivances employed go to the formation of these elements, auxiliaryand probably less important elements being incidentally involved.

The mechanical embodiment of my invention has been designed with a Viewto simplicity and compactness, and with aview to simple, positive andeffective operation,

and is such as to be operated directly by the operation of the primaryregister with which it is connected. I employ preferably an audiblemechanically operative alarm and ating parts; Fig. 3 is an elevationalview of v the locklng reglster mechanism removed from its su ortinmember the casin being also removed; Fig.4 is a view similar to Fig. 3,parts being broken away to show the mechanism for keeping count of thealarms; Fig; 5 is a side elevational view taken from the right side ofFig. 3; Fig. 6 is a side elevational view taken from the left side/ofFig. 3, parts being broken away to disclose the construction; Fig. is asectional view taken approximately on the line 7, 7 of Fig. 5,parts outof the line of section being included to complete the various kinematicchains of parts; Fig. 8 is a View similar toFig. 7, illustrating some ofthe parts shown in the latter figure ina different position; Fig. 9 is aView similar to F ig. 7

gear train shown in side elevation in' Referring first to Figs. 1 and 2,the primary register, whereby each collection is registered and thentotalized in. trips and also in sum, is shown at 15, this register beingmounted upon a supporting back plate 16 by way of catch lug 17, whichlug 18 of the register engages, and lug 19, which passes through theopening in the hasp lug 20, on the register proper, for the reception ofthe pivoted hook 21 which can be locked against removal by a padlockhung in the opening 22 thereof. This primary register has the trip totalindicator 23, the trip indicator 24, and the sum total indicator 25. Theactuating member for restoring the trip totalizing mechanism to zero andfor changing the trip indicator is shown at 26. As shown in Fig. 2, thisprimary registering mechanism is provided 'ith the main actuating member27, which swings through a predetermined are upon a central pivot 28,being normally held in the position shown in Fig. 2 by way of theexpansion spring 29, which is coiled about rod 30 between lug 31 on theback plate anc pin 82 on the rod, this rod being pivoted at 33 to theactuating member. The manner in which the operation of this actuatingmember secures the operation of the totalizing mechanism mechanicallyconnected therewith is not con cerned in the present invention, and nofurther explanation need be made as to that point. Suflice it to say,that each actuation of this member 27 in a counter-clockwise directionthrough a small arc, say, about thirty degrees, and its return in aclockwise direction to its normal position secures the registration ofone fare in this primary registering device. The initial actuation ofthis member 27, that is its movement in a counter-clockwise direction,is secured by way of a connecting rod 84 pivoted at 35 to the lower armof the member 27 and, at its other end, pivoted to one arm 36 of a bellcrank lever, which is rigidly secured upon a shaft 37, this shaft, wherethe device is employed by a traction company, extending the entirelength of the car so that registration may be made from any point. Thisshaft may be supported in any suitable manner, for instance in thebearing 38. The other arm'39 of the bell crank lever is provided with ahand strap 40, and it is apparent that a pull on this strap will swingthe bell crank lever to effect initial actuation of the member 27. Thereturn stroke of this member is secured by the expansion of the spring29.

The locking register of my invention is illustrated in Figs. 1 and 2 at41. The main supporting member of the locking register is in the form ofa back frame 42 having suitable slots 43, 43, in which an actuating pullbar 44 is slidably mounted, this pull bar being further guided byforwardly extending lugs 45, 45 upon a central portion 46 of the backframe 42. Screws 47, 47 are employed to mount the structure. This pullbar 44 has pivoted thereto at 48 a connecting rod 49, the other end ofwhich is pivoted to the pivot 35 on the actuating member 27. The motionof this pull bar 44 is further guided and defined by way of a screw 50,which passes through an elongated slot 51 in the pull bar and into theportion 46, this slot being straight and parallel to the motion of thebar and being of such length as to p mit full actuation of the member27. The pull bar 44 is provided with the actuating slot 52, which, inthe main portion, is slanted so that horizontal 11,1 roa mentioned inthe introductory statethis specification are mounted upon ments oi aback plate 53, as snown in rig. 3, and are contained within a casing orcover 54 suitably secured to this back plate by means of screws passingthrough openings 55, 55 therein. The back plate 53 is provided with thelugs 56, 56, which engage under the arches 57, 57 at the side of thesupporting frame and also with the bifurcated lug 58, which the lug 59,extending from the other side of the frame 42, is arranged to pass, apadlock member or a cotter pin 60 passing through an opening in this lug59 to retain the entire device rigidly against the supporting member. A.lug 58 may be provided at the back of the back plate to en gage theinside of the frame 42 to assist in supporting the various mechanisms.

Extending forwardly from the back plate are four properly disposed posts61, 61 of equal length, which support the secondary supporting plate 62,screws 63, 63 being provided to secure this plate rigidly in position.Between the back plate and the secondary supporting plate thestep-by-step mechanism and the directly associated parts are dis posed,while the sounding device is disposed upon the outer face of thesecondary supporting plate.

The various shafts and spindles are mounted in the two plates abovereferred to. The shaft is indicated by the character This shaft 64 hasrotatably mounted thereon a plate 65 which has a stud 66, of substantialdimensions, extending from the rear thereof and through segmental slot6'? in the back plate 53, this slot allowing for a substantialoscillation of the stud with the plate 65, about the shaft This studextends into the slot 52 in the pull bar 44, and it is apparent thatreciprocation of the pull bar will effect oscillation of the stud 66and, consequently, of the plate 65 about the shaft 64. Mounted rotatablyupon the shaft 64 above the plate 65, and oscillating with the plate 65,is a similar plate 68, between which and the plate 65 a dog is pivoted,will be pointed out. Immediately above the plate 68 a ratchet 69 ismounted upon the shaft 64, this ratchet being engaged by the drivingpawl '50 pivoted at 71 to the plate 68 and maintained in engagement withthe ratchet by means of tlie .Xpansion spring 72 disposed between thetail of the pawl and the post 73 on the plate Pivoted upon a stud 74,whicu extends from the back plate is a detent pawl 75, which is held inengagement with the ratchet 69 by means of a compresie variousmechanisms which have been ceeding tooth on the ratchet 69, the return imovement serving to rotate the ratchet through an arc equal'to onetooth, and the detent pawl at all times preventing movement in theopposite direction. The plates 65 and 68 are here shown as semicircular,this being sufficient to accommodate the various partscarried thereby,the plate 65 being notched, as shown at 78, for a purpose which.

will hereinafter fully appean Thus, the reciprocation of the pull baradvances the ratchet 69 step-by-step in the direction of the arrow at. r

Mounted upon the shaft 64: immediately above the ratchet 69, to which itis secured, is the circular locking cam 9, which is provided with anotch and a proximate tooth 81, the purpose of which will presentlyappear Mounted at a short distance from the shaft 64 is a spindle 82,upon which is rotatably mounted a pinion 8 f, which is provided with alocking pinion 85, preferably integral therewitl. This locking pinioncoincides with the pinion 8% except for the omission of a certain numberof teeth at regular intervals. In the spaces between the re- .mainingteeth the locking cam 7 9 is arranged to engage, and itis apparent thatduring practically the whole ofa revolution of this locking'cam thelocking pinion will beheld stationary by this positive engagement. Thetooth 81, which is provided upon the locking cam 7 9, is arranged forregular engagement with the pinion 8%. gagement can rotate the pinion 8%through a fraction of a revolution, since the adjacent tooth on thelocking pinion may then enter the notch 80 in the locking cam 79. Tn thecase herein shown for the purposes of illustration four teeth areprovided, and it is therefore evident that each engagement of the tooth81 with the pinion 8 1- will effect a quarter revolution thereof. Theseadvances being imparted to pinion 8% intermittently when the tooth 8i.and the notch 80 reach the spur and ocking pinion, respectively, the

pinion 84 will, at all other times, remain positively stationary becauseof the engagement between the locking pinion and the locking cam. Thisis the ordinary Geneva stop motion frequently employed in totalizingmechanisms. Movably mounted upon the shaft 64 over the locking cam 79 isa spur gear 86, which meshes also with the pinion 8%. This gear isrotated intermittently as the tooth 81 comes in contact with the pinion84:. This gear 86 has a basic disk This en- 7 87 secured thereto, andthe two parts form what 1 term a change wheel or an interchan eableunlts wheel the si nificance of which will hereinafter be made evident..

Rotatably mounted upon spindle 82and.

securely associatedwith the pinion84: is a" pinion 88, this pinion beingof larger diameter than. the pinion 84 and being in mesh with a spurgear 89 rotatably mounted upon the shaft 64. Mounted upon the shaft 64velocity ratio between gear 89 and pinion 88 and, pinions 84: and 88rotating in unison, .it follows that cam disk 90 will rotate at a speeddifferent than that of the change wheel to which I have referred and, ofcourse, from that of the locking cam 79, which rotates with eachregistration. The cam'disk 90 is made of approximately-the same diameteras the locking cam 79, as is also the addendum circle of the spur gear86, and the notches 9l'and 80 can, therefore,

come into simultaneous alinement with any of the spaces in the spur gear86. Pivotally mounted upon a post 92, which is suitably set between theback plate 53 and the secondary plate 62, is a follower 93, which isprovided at its forward end with the fol lower blade 94, whichisco-extensive in width with the locking cam, change wheel and cam disk,as'clearly shown in Fig. 5. This follower blade rests upon theperipheries of these three members, either one two, or all of them, andis held in this normal position, that is, the position shown in Figs. 8and 9, by means of a spring 95,

coiled about the post 92 and securing its leverage against post 96, setbetween the two plates 53 and 62, from which post the spring extends.When the notches 91 and 80 and a space in the change wheel come intosimultaneous alinenient with the blade 9%, the spring 95 causes thefollower to drop into these notches to efiect the positive locking ofall the mechanisms directly connected therewith, as will later bedescribed. It is while these mechanisms are so locked that the alarm orsignal is automatically given.

I contemplate the employment of an alarm which will be released foroperation immediately when the notches in the cam disk,

locking cam and change wheel register simultaneously with the followerblade.

ate this I provide means whereby the-alarm is wound properly andsutliciently in a minimum' interval and, associated therewith,.

means whereby the windingmechanism will cease to be-effective when thealarm mechanism is woundto that extent, regardless of whether moreregistrations are necessary to complete the block or not; This mechanismwill now be taken up for description.

Rigidly secured upon the spindle 97 which is mounted between the plates53 and 62, is

a ratchet 98, this ratchet being arranged to co-act with dog 99, towhich I have heretofore incidentally referred as being pivoted betweenthe plates and 68 on the shaft 64.

This pivot is indicated at 100. The tail 101 ofthis dog'is connectedby-means ofa tension spring102 with a stud 103 on the back plate'53, andby this means the dog is normally maintained in engagement with the,

ratchet 98. The oscillation of the plates 65 and 68 which has heretoforebeenreferred to is effective in rotatingthis ratchet and its shaft inthe direction of-the arrow Z). Also securely mounted-upon the spindle97, but distanced from the ratchet 98 by means of a separating piece104:, is a pinion 105, which meshes with a spur gear106securelymountedupon the spring shaft 107, which, in turn, is mountedbetween the backand secondary plates, as has beendescribed withreference to vtheuother shafts; A spiral spring 108 surrounds the shaft107 one end of the spring being securedto the shaft, and the free end ofthis spring is secured conveniently to thepost 96.- Mounted upon thepivot post 109,'which is set between the back and'secondary plates, is a-detent pawl 110, which is held inqconstant engagement with the ratchet98 by means of'a spring 111, coiledabout the post109 and securing itspurchase by'its connectionwith post 112, as shown" in the drawings. It"is now apparent that-theoscillation of the plates 65and 68 toreciprocate the dog 99 gradually winds the spring 108 by a step-by-stepaction.

In order that the winding of the alarm mechanism maybe properly timedand limited as has heretofore been pointed out, I provide mechanism asfollows: Near the shaftlOY- a parallel shaft 113 is mounted in the backand secondary plates. This shaft 113 "is*operatively connected with theshaft 107 and -is-geared down byway of a gear trah 114,=115, 116, 117,118, 119, pinion 114 'tei'ng rigidly "secured to the shaft-1Q? and gear119 being secured to the sleeve 120 rotatably mounted on shaft 113. Thissleeve 120 carries the dog 121, which has a forwardly extending lug 122,and it is apparent thatthis dogwill respond in movement to both thewinding and the running down of the alarm system. Carried upon a sleeve123, which is rotatably mounted upon the shaft 107, is the lever 124,one arm of which extends over the dog 99, and is provided at its endwith the rearwardly extending lug 125. he other arm of the lever extendsin the opposite direction and, by way of a spring 126, which findspurchase on one of the posts 61 and is coiled about the sleeve 123, isnormally held against sleeve. 120 on the pivot post 113 as a convenientabutment. The tail of the lever 124:,that is, the part upon which thespring 126 operates, has a contact surface 127, which is arranged forengagement by the upwardly extending lug 122 of the dog 121. hen thealarm mechanism is being wound, the dog 121 moves in the direction ofthe arrow 0 and, at the in stant that the alarm mechanism has been woundto the proper extent, this engagement between the lug 122 and thecontact surface 127 takes place to move the lug 125 on the other end ofthe lever 1241 into the path of a forwardly extending lug 128 on the dog99. As will behereinafter pointed out, the lug 128 will be in positionto be engaged by the lug 125 at this time; This will move the dog 99 outof engagement with the ratchet 98. Mounted upon the post 96 is an anchor129, the lower end of which is provided with a hook 130, which is heldtoward a boss 13]. on the dog 99 by means of the free end of the spring95, which is coiled about the post 96 and which has already beenreferred to as used for another purpose. The relation between thisanchor and the dog 99 during the winding of the alarm mechanism, thatis, while the dog advances in the direction of the arrow 0, is shown inFig. 8. Asthe dog 99 reciprocates, the anchor 129 is free to travel withit, as shown in Fig. 8.. WVhen, however, the dog 121 reaches itsfarthermost position in traveling counterclockwise, the lug 125 of thelever 12% engages the lug 128 on the dog 99, lifting the dog out ofengagement with the ratchet 98 and into engagement with the anchor 129,byway-of the boss 131. The dog 121 and the dog 99 are so relativelytimed that the lug 128 on the dog 99 will, in its reciprocatingmovement, be in the path of the lug 125 when the latter is raised, ashas heretofore been explained. The dog 99 being thus thrown out ofengagement with the ratchet 98, the parts assume the positions shown 111Fig. 9, from which it will be clear that the anchor 129 is free to swingon the post 96 to respond to the movements of the dog 99 mant a-idle ae, made, the latter being always held out of engagement with the ratchet98. Thus, all registrations after this actuation of the lever 124 areineffective in' securing any further winding of the alarm spring. Whilethese further registra tions are being made the ratchet 98 is en gagedby the detent pawl 110 to prevent.

any movement thereof.

I shall now describe the mechanism for by the upper side of thefollower, as clearly shown in Figs. 7, 8 and 9. Thisconnecting piece134, at the side nearest the oscillating part'65, is provided with anotch 136 which, when the follower 93 is permitted to drop, is broughtinto engagement with the notch 78 in the plate 65 so as to operativelyconnect these two parts.' The free end of the spring 111, which hasalready been referred to, is connected with a stud 137 on the connectingpiece 134, so that this action just pointed out may follow. Thus, afterthe connecting member 134 is allowed to drop, the next registration,oscillating the plate 65, will, upon the return movement, cause theco-action of the two notches to lift the detent pawl 110 out ofengagement with the ratchet 98. This position is shown in Fig. 10. It isseen that the spring of the winding mechanism is then free to unwind.This locking of the two notches prevents complete return of'theoscillating plate 65 and an operator is therefore unable to secure theadvance of the ratchet 69. Thus the mechanism is locked againstoperation.

To operate the alarm and to properly restrain the unwinding of thespring 108 an escapement train is provided. This arrangement is asfollows: Mounted upon the spindle 97 and operatively carried with theratchet 98, but being distanced therefrom by a spacing plate 138, is aratchet 139,-

with which a pawl 140 pivoted to a' spur gear 141, loosely mounted onthe shaft 97, is held in engagement by means of a spring 142. Thus, whenthe alarm mechanism is being wound, the ratchet 98 and the ratchet 139move together in the direction of the arrow 6 without in any wayeffecting the spur gear 141. This spur gear meshes with the pinion 143mounted on a spindle 144, this pinion being operatively connected withan escapement wheel 145 by way of a sleeve 146. The escapement wheel 145is engaged by a pallet piece 146 secured upon a verge 147 passingforwardly through the secondary plate 62. Lateral displacement of thisverge is prevented by means of a cotter pin 148 passing therethrough, asshown in Fig. 6. At its forward end this verge 147 is provided with aspring mounted hammer 149,

hammer may engage the inside thereof in:

accordance with the oscillations of theverge. The verge 147 and thehammer 149' serve not only as a convenient means to sound alarm, butserve'as well as an escapement for timing the alarm.

As has been before pointed out, the dog 121 will rotate in a clockwisedirection when the alarm is being given. The lug 122 on thisdog isarranged also for engagement with an extension 129 on the anchor 129 andalso with the tail of the follower 93.

These engagements take place when the alarm mechanism has run down andwhen the dog 121 has reached its farthermost position in the clockwisedirection. The engagement'of the lug 122 with the extension 129 liftsthe hook 130 out of engagement with the boss 131, so that the dog 99 maydrop back into engagement with the ratchet 98. The engagement of the lug122 with the tail of the follower 93 lifts the follower out ofengagement with the notches in the looking cam, the cam disk and thechange wheel, and also lifts the connecting piece 134 out of engagementwith the oscillating plate 65. This particular arrangement is shown inFig. 7. Detent pawl 110 is permitted to drop back into engagement withthe ratchet means of a bolt or nut 152, which clamps into place a yoke153 passing over to the corner of the secondary plate 62 and under thehead of the retaining screw 63, hereinbefore referred to. Mountedbetween the secondary plate 62 andthe yoke 153, near the bell 150, is aspindle 154, and upon this spindle is securely mounted, directly overthe plate 62, a ratchet 155. Thisratchet' is engaged by an'actuating dog156, a spring 156 being provided to maintain such engagement, which ispivoted at 157 to a crank 158 which, in turn, is keyed upon the shaft113 upon which, it will be remembered, the dog 121 is secured. The dog121 rotates in a clockwise direction, arrow 03, when, and only when, thealarm operates. This movement of the dog 121 and consequently of theshaft 113 advances the ratchet 155 one unit in the direction of thearrow e by way of the dog 156, this dog being so formed that movement ofthe shaft 113 in the opposite direc-- displacement by means of a cotterpin extending therethrough, as shown in Fig. 6, and the forward end ofthe shaft has secured thereto a disk 163, upon which a series of numbersor other indicating characters, corresponding in number to the teeth ofthe ratchet 155, are placed. The disk is of such diameter that thesenumbers may come, one by one, before an opening 16% in the casing orcover 5a, (Fig. 1), as indicated in dotted lines in Fig. 3. By thisarrangement it is apparent that count of the number of times that thealarm has been released may be kept. As indicated in Fig. 1, sound holes165, 16-5 are provided in the casing for obvious purposes.

The construction and operation of the Various mechanisms having now beendescribed, I shall append a brief summary of the operation of the deviceas a whole and will also explain the various results secured: The reistrations in the primary registering device reciprocate the pull bar 1%and consequently move the locking cam 7 9 in a counter clockwisedirection. The normal position of the oscillating plate is shown in Fig.7, and its extreme position is shown in Figs. 8 and 9. Fig. 10 shows theoscillating plate on its return movement. During the rotation of thelocking cam 79, the intermittent engagement of the tooth 81 carriedthereby causes the simultaneous rotation, but at different speeds, ofthe change wheel and the cam disk 90. It now appears that the lockingpoint is that instant when the notches 91 and 80 and a notch in thechange wheel register simultaneously with the follower blade 94;. Thechange wheel herein shown is such that at no time will it interfere withthe drop of the follower if the notches 90 and 81 are in registertherewith. This, however, is merely. a special case and, for thepurposes it is contemplated that the basic disk 87, which has beenreferred to, be built up at any desired point or points so that thedropping of the follower can be prevented at any desired time. In thestructure which is herein shown for the purposes of illustration, theratchet 69 has eleven teeth, and it follows that with every eleventhregistration the notch 80 will be in alinement with the follower blade9%. From previous description it is clear that the cam disk 90 rotatesbut a fraction of a revolution with each complete revolution of thelocking cam 79. If it be assumed for the purposes of illustration thatthirteen revolutions of the locking cam are required for one completerevolution of the cam disk 90, it follows that notches 91 and 80 will bein alinement with th follower blade 94: every 143 registrations. Andsince, in the embodiment herein shown, the change wheel is such as notto interfere with the dropping of the follower blade at any time, itfollows that an alarm will be given every 1 13 fares. It is clear thatif, when the notches 91 and 80 are in alinement with the follower blade9%, the registering part of the change wheel be built up to the extentof the addendum of the gear 86, any

movement of the follower blade 9% will U6 prevented. it is furtherapparent that this basic disk of the change wheel could be built up inany way to interfere with the dropping of the follower blade at any timethat the notches 91 and 80 are in alinement. Assuming, for the purposesof illustration, that the change wheel has thirty-one notches, that is,the gear 86 has thirty-one teeth, it follows that the complete cycle is31 (148, 01' M33 registrations. So it follows that the intervals betweenlocking points are multiples of 1 13. lVithin the limit of M33registrations to the cycle any variation in the number of periods can beobtained by merely building up the basic disk of the units wheel.

To summarize, it may be said that a theoretical cam is divided intothirty-one spaces each composed of 1 13 units to make up the total cycleof lies registrations. If there is one operating point, for instance, anotch, the register will lock once for 4&33 registra tions. If twonotches are provided, it will lock twice in that time, and so on so longas the blocks are multiples 14:3.

The above numerical discussion is provided merely for the purpose ofillustration, and I wish it to be understood that 1 contemplate anycombination and permutation of intervals. In fact, it is the very objectof my invention to provide for such scope. The number of teeth in thespur gears and ratchets above mentioned are merely exemplary, and I donot wish to be understood as limiting myself to any particular number.Thus, while the registrations are being made the follower blade ridesupon the periphery of the cam disk, change wheel and locking cam, andthe dog 99 is operated to rotate the ratchet 98 whereby the spring ofthe alarm mechanism is wound. During this period the dog 121 rotates ina counterclockwise direction and, at that instant when it is woundsuh'iciently, the lug 122 of the do 121 engages the lever 12% to throwthe dog 99 out of contact with the ratchet- 98 and into engagement withthe anchor 129. It is possible that this might be a locking point,since, as before stated, the dog 121 travels its full stroke during aminimum period. However, if the change wheel is such that the currentinterval is longer, it is clear that the dog 99, being held by theanchor 129, may reciprocate in accordance with the registrations,without in any way affecting the alarm mechanism. Vhile the followerblade 91 rides upon the cam peripheries, the connecting piece 13: isheld out of the path of the oscillating plate 65 and, con:

sequently, the detent pawl 110 is left in engagement with the ratchet 98to prevent release of the alarm mechanism. When, however, a lockingpoint is reached, the follower .blade 94: drops and'the connecting piece13-1 falls into operative relation with the oscillating plate 65, sothat the return stroke on that registration lifts the detent pawl 110out of engagement with the ratchet 98 so that the alarm mechanism isfree to operate. This also looks the mechanism. TVhile the alarmmechanism runs down the dog 121 rotates in a clockwise direction, as hasheretofore been described, and finally the lug 122 thereon comes intoengagement with the anchor 129 and the'tail of the follower 93. Theengagement between the lug 122 and the anchor 129 restores the dog 99 tothe ratchet 98, and the engagement between the lug 122' and the tail ofthe follower 93 raises the connecting piece 13% out of contact with theoscillating plate 65, so that the detent pawl 110 may once more dropinto engagement with the ratchet 98. alarm mechanism is stopped,theparts being then in the position shown in Fig. 7. The engagement ofthe connecting piece 134 and the plate 65 prevents complete return.

he plate so that the pawl carried thereby can not catch the succeedingtooth of the associated ratchet. This prevents another registrationuntil the alarm mechanism has rundown, so that an attendant is unable tocut off the alarmfby immediately making another registration. Thesounding of the alarm requires the same interval each time, as thespring is wound to the same tension and the dog 121 must travel enoughthe same angular distance before the parts are unlocked. It is evidentthat the length of time that the mechanism is toremain locked may bepredetermined in accordance with operating conditions. The parts are nowin position for .the beginning of another interval. As the winding ofthe alarm mechanism takes place, which mayor may not constitute entireinterval, as has heretoforebeen explained, the parts are in the positionshown in l i 8, the dog 121 then rotating in the direc ion of the arrow0. The

position of th parts, when the alarm mechanism has been woundsufficienly and when the actuating dog is thrown out of engage- V ment with thealarm ratchet, is shown in Fig. 9. Fig. 10 showsthe position of theparts when the alarm mechanism is running down and'the dog 121 is,consequentiy, rotating in the direction of the arrow (Z, the particularposition being just before the lug 122 actuates the cam follower and heanchor. jBy way of the ratchet 139 the escapement mechanism heretoforedescribed is connected with the alarm mechanism so as to ring the belland restrain the alarm spring when the alarm ratchet has been released.7

Thus the It is to be noted that the particular registration whichsecures the looking, as pointed out in the foregoing summary, is thatregistration which terminates a particular period or block ofregistrations. As pointed out,

each registration secures a complete oscillation of the plate 65. Theinitial stroke of each oscillation secures the advance of the windingmechanism and of the cam mech: anism. The return stroke of thatparticular registration which terminates a block secures the release ofthe alarm ratchet from the associated detent pawl, but is curtailed soas not to secure advance on the feeding ratchet. Thus, all theoperations which have been described are secured by way of the simpleoscillation of the actuating member of the primar registering device, sothat the employment of the locking register of my invention entailsmerely the simple mechanical connection between it and the primaryregister used in any event.

' The device of my invention maybe used effectually as a p imaryregister when individual indications are not required and in such a casetallyis made at each of the. locking points. t might also be here men-'ioned that an electrically operated alarm maybe substituted for themechanical alarm herein shown where the former could be usedadvantageously. V

It is to be noted that all primary registers commercially used in thepresent day are operated either by an oscillatory or a reciprocatorymovement and it is clear that the device of my invention may be readilyadapted to all these primary devices. In order that the requiredoscillatory movement of the actuating stud of my device may be securedwhatever he the stroke of the associated primary register, the ends ofthe actuating slot in the pull bar are elongated and c .posed parallelto the movement of the bar, thus permitting a dwell of the actuatg studuntil the stroke or throw of the imary device is completed.
